Frequently asked questions about Septic Tank Cert
Do I need permission to install a septic tank?
You need Building Regulations approval for all new septic tank installations. In England, under the general binding rules, a septic tank that discharges directly to a watercourse must be connected to a public sewer, replaced with a small sewage treatment plant, or given a drainage field. You may also need an environmental permit. Wales, Scotland and Northern Ireland have their own regulators and rules.
What is the difference between a septic tank and a treatment plant?
A septic tank provides primary settlement only and must discharge to a drainage field (soakaway). A sewage treatment plant includes secondary biological treatment and can discharge to a watercourse with the appropriate permit. Treatment plants are required where no drainage field is viable.
